The speed of development of water-based coatings will be greatly increased

Water-based coatings
been widely promoted in China for more than ten years, but large-scale applications encountered certain obstacles. With the implementation of a series of environmental
policies and laws and regulations involving
coatings industry, with the upstream and downstream are beginning to pursue non-toxic environmental protection, the spring of water-based coatings really came.
Department of Environmental Protection of Shandong Province on the paint industry involved in environmental protection policies and laws and regulations have been interpreted. He believes that whether domestic or foreign, effectively crack the paint production and use of VOC (volatile organic compounds) pollution emissions problem is imminent. It is understood that the VOC emissions of water-based coatings are less than 1/10 of solvent-based coatings. "On April 24, 2014, the strictest environmental protection law in history was officially released," he said. As one of the key industries producing VOC pollution, the coating industry needs to carefully analyze the law and formation mechanism of pollutant discharge, explore the new path of environmental protection from the aspects of product structure adjustment, process control and end management, and embark on a new industrialization road with low energy consumption, low pollution, high efficiency and sustainable. According to
, with the tightening of environmental regulations in various countries, consumer awareness of environmental protection, the rapid rise of water-based polyurethane coatings, has been widely used in fabrics, leather, adhesives and other fields, in
wood coatings
,
building coatings
,
automotive coatings
,
plastic coatings

,
anti-corrosion coatings and other fields have also emerged. Zhao Xiao (blog) Dong, chairman of the water-based polyurethane committee of the China Polyurethane Industry Association, said the EU has strict limits on VOC emissions in the production of coatings. Water-based coatings to water as a dispersion medium, with non-toxic environmental protection, odor-free, volatile very few, non-combustible non-explosive and other advantages, no harm to the human body, representing the development direction of the paint industry.
participants pointed out that the equipment technology that has restricted the promotion and application of water-based coatings has matured, while the environmental awareness of downstream users is also improving, many large furniture factories have begun to use water-based coatings, the market to guide the paint industry to make the right choice.
, the cost and price problems that have long hindered the large-scale application of water-based coatings have been solved, and the prospects for the development of water-based coatings are bright. "We have been promoting water-based coatings for more than ten years, and have done a lot of work in technology development and application, and now we have finally seen the dawn, " said Yu Zhonghua, chairman of the water-based coatings branch of the Coatings Special Committee of the China Chemical Society. The cost of mass production was reduced after the paint oil was changed to water. One of our member companies, at the beginning of the year water-based coating costs than solvent-based 30% higher, the current cost of water-based coatings than solvent-based products is 2% lower. "
but there are some industry insiders remind that there are still some problems in the development environment of water-based coatings. Zhao Xiaodong pointed out that the problem is that the development of the region is not balanced, environmental standards are inconsistent, to a certain extent, affecting the demand of the water-based paint market;industry view
expanding the application needs to go upstream and downstream hand in hand
Zibo Jiafeng Chemical Technology Development Company General Manager Yang Jiafeng: water-based coatings applications also need more benchmark enterprises. Earlier this year, the domestic furniture industry well-known enterprises Qumei furniture first announced the use of water-based coatings, but such enterprises are still too few. In terms of technology, Jiabao and other national enterprises of water-based coating technology has been very mature, breaking the foreign enterprises' technology monopoly pattern. Once the market for water-based coating products is launched on a large scale, the coatings industry will achieve leapfrog progress. This is a period of change, the industry enterprises to seize this rare opportunity.
Jiabao Chemical Group Water Paint Division General Manager Zhu Yanan:
wood paint
water-esque voice is getting higher and higher, and
water-like wood paint
research and development efforts and product performance has been greatly improved, but now the water-like wood paint market hot, cold market situation still exists. In the end, the main reason is that the water-based coating drying process is significantly larger by temperature and humidity than solvent-based coatings, resulting in the existing coating drying equipment directly used in
water-based wood coatings

But with the introduction of a nationwide policy document restricting solvent-based furniture wood paint and encouraging the use of water-based wood paint, it is an irreversible trend for furniture to replace traditional solvent-based wood lacquer with water-based wood paint. How to improve the existing coating production line to adapt to the construction of water-based wood coating has become a reality that must be faced.
Wuhan University of Engineering School of Chemical and Pharmaceutical Professor Yan Fuan: water-based industrial paint according to the use can be divided into water-based wood paint, water-based metal paint, water-based plastic paint and water-based glass paint, its core component is
filmed substances
is a water-based resin. Among them, water-based polyurethane coating is based on water-based polyurethane resin, water-based dispersion medium preparation of coatings, with low toxicity, not easy to burn, do not pollute the environment, energy saving, safety and other advantages, but also has solvent-based polyurethane coatings some properties. The advantages of high hardness, strong adhesion, wear resistance and good flexibility of polyurethane coatings are combined with the advantages of low VOC emissions of water-based coatings, which has broad prospects for development. Industry and research institutes should strengthen cooperation to jointly promote research and development and marketing of water-based coatings, and accelerate the pace of industrial adjustment and upgrading.
